Abstract:
We used recently collected and historic data to evaluate effects of water temperatures on passage of adult salmon and steelhead in the lower Snake River, especially in relation to temperature exposures in fishways. Similar to the findings of others, we found little evidence that water temperatures have increased over time at the mouth of the Snake River (downstream from Ice Harbor Dam) but temperatures in the forebay of Ice Harbor Dam have trended upwards in the fall (September and October) since 1962. The latter trend can be explained at least in part by an increase in air temperatures during August and September in the region since 1948.
